Idon't understand this question

did grant's government do too much or too little to reinforce reconstruction?

-- consider both sides

A primary focus of Grant's administration was Reconstruction, and he worked to reconcile the North and South while also attempting to protect the civil rights of newly freed black slaves

An example of  “trust-busting” that Theodore Roosevelt enforced is that he supported the Northern Securities Company.

Trust busting refers to the manipulation of an economy, carried out by governments across the world seeking to prevent or eliminate monopolies and corporate trusts.

Theodore Roosevelt promoted a public relations image of being a trust buster  through his regulatory reforms and anti-trust prosecutions.

The Presidency of Theodore Roosevelt began on September 14, 1901.
